FIELD OF THE INVENTIONIn systems for preventing infection by germs in aircrafts, trains, buses, ships hospitals, nursing homes, restaurants, schools, lifts and breathing systems using air during emergencies
STATE OF THE ARTVehicles, hospitals, restaurants, schools and the like, lack good protection against germs. The masks in addition to being expensive are not effective, they partially filter, they do not protect the wearer or those around them. This is very important when there are epidemics, since it is difficult to isolate the public, generally due to lack of space. Neither is a correct air renewal carried out. Aircrafts use the dangerous oxygen for breathing in case of emergency, depressurization, etc. Oxygen transported in cylinders or chemically generated is currently used. With the present invention air is used, both for normal breathing and in case of emergency instead of oxygen. The present invention prevents contagion and/or destroys all kinds of germs.
DESCRIPTION OF THE INVENTIONObjective pursued with the present product and its advantages.
Provides a system that: Is simple, inexpensive, and useful that prevents or destroys viruses, bacteria and protozoa or parasites.
Make the sick independent in hospitals and vehicles, using an independent fresh air circuit:
Avoids the use of oxygen and therefore its danger.
It allows the use of fresh air individually and substitutes oxygen in emergency. It can be used even in case of smoke or fire, which is not possible at present with oxygen.
It can increase a little the pressure and the quantity of oxygen applied as the air is cleaner. It has more oxygen than the recycled air. The applied air can carry more moisture without damaging the aircraft's structure. Fresh air applied is cheaper because the amount is smaller It is not affected by the exhaled air that carries microbes, CO2, ethanol and aldehydes. It is very important to avoid viruses on airplanes, due to its high expansion speed it can contaminate many cities and very quickly.
CURRENT PROBLEMIn vehicles and other closed places, even open ones with a lot of staff, it is very difficult to avoid the spread or contagion of diseases. Being forced to keep distances that make them unprofitable. The masks are not effective, they partially filter, they do not protect the wearer or those around them. As an example, FFP-2 and FFP3 with valve, if the wearer is infected he exhales and the microbes are not filtered out during exhalation. Not being able to travel causes a great economic deterioration. On the other hand, bad smells among passengers are avoided. In aircrafts, cabin air and oxygen are used in the event of an emergency, but cannot be used with cabin smoke. There is no protection for passengers in adjacent seats. Being heavier than with the air system, and more dangerous especially if the oxygen generators are used.
The germ protection system for vehicles, hospitals, restaurants, schools, nursing homes, lifts and the like uses:
a) A system that prevents germs: bacteria, protozoa, viruses or parasites from being breathed in vehicles or closed premises, lifts or the like, blowing or sucking air,
b) An independent air installation that applies air conditioning, fed with turbofan engines, to the individual air blowing nozzles in the ceiling or backrest of the compartments of each passenger,
c) An independent air installation using compressors that extracts and compresses the outside air, and apply it to the individual air blowing nozzles in the ceiling or backrest of the compartments of each passenger,
d) A system that uses an individual installation to replace oxygen system in case of emergency,
e) A system that is valid simultaneously for protection against germs and for breathing in case of emergency. The air is filtered, disinfected, its pressure, temperature and humidity regulated, and through some ducts it is applied in these compartments, the masks, helmets, hoods, their ducts or nasal cannulas are stored, which are directly connected to the air installation, or carries mouthpieces, fittings, quick connector, nozzles sockets, where the ends of the ducts of the masks or portable cannulas are attached and
f), A system that is coupled to the individual air supply nozzle of the passengers, using for this purpose at the end of the duct of the mask, face mask screen, diving suit or helmet, a hood with at least one semi-annular, semi-thorax or semi-oval suction cup which, when pressed, adapts and attaches to the chassis or panel carrying the air supply nozzles (48) of the air conditioning system of the aircraft or vehicle.
In vehicles and especially in aircrafts, air is blown in from the air conditioning, in the seat area where the passenger inhales. The air can come from gas turbines, the system of most current aircrafts, or from some compressors that get it from the outside of the aircraft or vehicles, thus avoiding contamination of the air conditioning by oil leaks from the engines or turbines.
In vehicles and especially in aircrafts, the passenger can be blown or sucked in air by: 1) grooves in the area of the seat close to the head, 2) rotating or flexible hollow arm-jets, or 3) masks and some ducts. You can also create an area or space around the head, where the air is blown or sucked, an area that can be formed or obtained and surround with: a) a flared cover, b) a cap that is fastened simultaneously covering the backrest and part of the area of the head, c) a cap that rotates and extends partially covering the head, d) a cap with protruding side flaps that simultaneously carry grooves through which air is blown, e) some curtains that extend partially covering the front area of the head and f) some lateral plates or sheets that can be flexible, in the form of a bellows or a fan. These previous systems create a semi-independent chamber around the passenger suction zone, where the air is blown a slightly pressurized area is produced. Individually, controls control the air flow and temperature. The air for the seats can be taken from the air conditioning installation on the floor or on the side or roof of the vehicle. The blowing of air from the grooves or hollow arms jets will preferably be carried out in the upper areas of the backrests with filtered and disinfected air.
Air Blown into a Person's Suction Area, with or without a Cover or Hood, Increases the Pressure of the Person, Preventing Contaminated Air from Entering.
Air suction can also be carried out in small compartments made with partitions or curtains, suctioning in each one of them with silent extractors and in the case of aircrafts taking advantage of the external atmospheric depression. The suction can be done through ducts from the floor or the side of the vehicles. Suction will preferably take place in the lower lateral area of the backrest or seat. In the elevators, air extractors are placed in the lower lateral area, adding an air inlet opening in the upper area: Both are protected with grilles.
In restaurants, coffee shops, hospitals, nursing homes and schools, rooms or rooms can be subdivided by partitions, partitions or curtains into small divisions or compartments, applying to each of the compartments obtained the aspiration of air by means of individual silent extractors. This can also be done by applying or introducing a general flow for each room, which can be the air conditioning, and applying an outlet hole in each of the divisions or compartments. In this way, the clients or patients who occupy them become independent and protect each other.
The air conditioning system pressurize and condition the cabin temperature and humidity with the turbofan engines. It is characterized by the fact that for both individual standard and emergency breathing are used:
a) The air conditioning system and its corresponding independent installation,
(b) Some compressors using external air and its corresponding separate installation or
c) The air conditioning system is normally used and the compressors in case of emergency. For this purpose, the air is filtered, disinfected, its pressure, temperature and humidity regulated, and through some ducts it is applied in compartments in the ceiling or in the backrest of the passenger seats, including the cockpit crew areas. In these compartments, the masks, helmets, hoods, their ducts or nasal cannulas are stored, which are directly connected to the air installation, or carries mouthpieces, fittings, quick connector, nozzles sockets, where the ends of the ducts of the masks or portable cannulas are attached. A tongue-and-groove coupling can be made lengthwise, by pressing and overcoming some retainers, with a quarter turn at the end, or by threading or hooking them. This system is valid simultaneously for protection against germs and for breathing in case of emergency.
The masks may be fixed in the compartment or they may be portable and attached to the end of their duct or fitting, tongue and groove or by modifying the flow control knob (51) in the case of current aircrafts.
Compressors are powered by standard electrical power, emergency power or batteries.
Can be used a) Modified current typical ceiling blowing nozzles, (b) Factory-modified air blowing nozzles whose manual knob is shaped divergently outwards or a retainer is applied, or (c) Blowing air nozzles on the seat backrest.
The air conditioning is blown from the bleeding of the turbofan engines, using ducts that take it to the air blowing nozzles in the ceiling or backrest or air is obtained from the outside of the vehicle is blown into the nozzles with compressors.
The current blowing nozzles can be modified adding a retaining ring, a sealing ring, an annular channel, a retaining ring to the manual flow adjustment knobs of the nozzles. They can be modified adding an adapter, with a flange that is fixed to the chassis using screws or an adhesive that allows the tongue and groove connection with the duct end fitting or nasal cannula.
A flared chamber covering the head of a passenger, is connected by a duct to a fitting in the seat backrest. The ducts or nasal cannulas carry the flow regulating valves along. Tooth or teeth embedded on the manual knob, acts as a retainer. An external thread is screwed onto the manual knob, acting as a retainer.
A variant can blow the air through diverging nozzles to widen the application area, slow down and pressurize the area. This can occur through multiple holes or slots in the seat back.
All types of masks can be used, but mainly they must allow the CO2 to escape or otherwise lead it to the outside of the aircraft or vehicle through a conduit.
The
The intermediate adapter (55) allows tongue-and-groove connection with the duct end fitting or nasal cannula.
With both of the above systems, no modifications need to be made to the aircraft.
